UGC NET CSE | August 2016 | Part 3 | Question: 23
Let $\Sigma= {a, b}$ and language $L = {aa, bb}$. Then, the complement of $L$ is $\left\{\lambda, a, b, ab, ba \right\} \cup \left\{w \in\left\{a, b\right\}^{*} | |w| > 3 \right\}$ ... $\left\{\lambda, a, b, ab, ba\right\} \cup \left\{w \in \left\{a, b\right\}^{*} | |w| \geq 3 \right\}$
